摘要：

目的  分析磁共振扫描弥散成像（magnetic resonance diffusion-weighted imaging，MR-DWI）和多层螺旋CT（multi-slice spiral CT，MSCT）在原发性腹膜后肿瘤（primary retroperitoneal tumor，PRT）中的评估与应用价值。

方法  选取原发性腹膜后肿瘤患者67例的临床资料进行回顾性研究，经病理学检查确诊为恶性病变共45例（恶性组），良性病变共22例（良性组），均行MR-DWI、MSCT扫描检查，且对不同方法检查后的阳性检出率、阴性检出率、误诊率、漏诊率、敏感度、特异度进行观察及评估。
结果  原发性腹膜后肿瘤患者67例经病理确诊结果显示，按PRT病变起源分类为神经源性23例、间叶组织来源27例、生殖细胞源性8例、淋巴组织源性7例、其他2例；按肿瘤性质划分为恶性45例、良性22例。MR-DWI的误诊率、漏诊率低于MSCT（P＜0.05）。MR-DWI的AUC为0.988，敏感度93.33%，特异度86.36%；MSCT的AUC为0.748，敏感度75.56%，特异度45.45%。
结论  〖JP2〗MR-DWI用于原发性腹膜后肿瘤诊断，其准确率高于MSCT，并能为肿瘤的良恶性诊断以及临床治疗提供客观依据。

Abstract: Objective  To analyze the evaluation and application value of magnetic resonance diffusion-weighted imaging(MR-DWI) and multi-slice spiral CT(MSCT) in primary retroperitoneal overlying tumor(PRT). 
Methods  A retrospective study was conducted on the clinical data of 67 patients with primary retroperitoneal overlying tumors. A total of 45 cases were diagnosed as malignant by pathological examination(malignant group), 22 cases of benign lesions(benign group) were all given MR-DWI and MSCT examination, and the positive detection rate, negative detection rate, misdiagnosis rate, missed diagnosis rate, sensitivity, and specificity of different methods were observed and evaluation. 
Results  A total of 67 patients with primary retroperitoneal overlying tumors were diagnosed by pathology. The results showed that according to the origin of PRT lesions: 23 cases of neurogenic origin, 27 cases of mesenchymal tissue origin, 8 cases of germ cell origin, 7 cases of lymphoid tissue origin 2. The other 2 cases. According to the nature of the tumor: 45 cases were malignant and 22 cases were benign. The misdiagnosis rate and missed diagnosis rate of MR-DWI were lower than MSCT(P＜0.05). The AUC value of the area under the curve of MR-DWI is(0.988), the sensitivity was 93.33%, and the specificity was 86.36%. The AUC value of the area under the curve of MSCT was 74.80%, the sensitivity was 75.56%, and the specificity was 45.45%. 
Conclusion  MR-DWI is used for the diagnosis of primary retroperitoneal tumors. Its accuracy is higher than that of MSCT, and it can provide an objective basis for the differentiation of benign and malignant tumors.
